OpenSSL self-built certificate SSL + Apache I have prepared it. Well, the following is my note. For details, enter the author name: wingger.In this article, we will test the certificate on Linux9 + apache2.0.52, tomcat5.5.6, j2se1.5, and openssl0.97.The purpose of this article is to communicate.

In order to ensure data security in a particular environment, it is sometimes necessary to enable SSL functionality. The following is an example of a serv-u server that describes how to enable SSL encryption. Creating an SSL Certificate To use the Serv-u SSL feature, you will of course need the

Currently, many websites or services are implemented based on SSL and can be accessed only after certificates are downloaded and installed. If it can provide download, of course there are any problems. However, if you do not have permission to download and it is not a CA certificate, it is only a self-Signed server certificate. Only know its port and address. If you forcibly access it through a program, you may get the following error: javax.net.ssl.

First, you need to understand some basic concepts before installing 1. Certificates used by SSL can be self-generated or signed by a commercial ca such as Verisign or thawte. 2. Certificate concept: First, you must have a root certificate, and then use the root certificate to issue the server certificate and customer certificate. Generally, the server certificate and customer certificate are in a hierarchical relationship. The root certificate and

In the past, I heard people say that an IP address can be used to generate a certificate. Today, the example shows that IP addresses cannot be used.Scenario 1: The name specified when the certificate is generated is IP Address The example is an example of single-point logon. The configuration in Web. XML is as follows: If the HTTPS protocol is specified in the above configuration and the name specified during certificate generation is 172.18.113.78, an error occurred while accessing the certi

If our site projects are not important business sites, such as personal sites, blogs or simple projects need to use the SSL security certificate, in fact, the Internet currently provides a free SSL certificate enough for us to choose and use.

This article describes how to configure SSL support in Tomcat. 1. It is easier to configure SSL support in Tomcat. There are several steps: (1) If the JVM version is earlier than 1.3, You need to download JSSE, which is a Java SSL support library. Since JDK 1.4, JSSE has been built into JDK. Therefore, this step can be omitted. (2) execute the command (in Linu

There are many scenarios for using SSL on Python, and my main concern is to use Python to access HTTPS resources and to use Python to provide HTTPS services. (HTTPS is one of the SSL applications on the Web)I. Using python to access HTTPS websitesThis should be the simplest and most common scenario. We use Python as a client to access the public Web site, and this site for the transmission of security (to a

First, what is HTTPS? According to Wikipedia's explanation: Copy Code code as follows: Hypertext Transfer Security Protocol (abbreviation: HTTPS, English: Hypertext Transfer Protocol Secure) is a combination of Hypertext Transfer Protocol and SSL/TLS to provide encrypted communication and identification of network server identities. HTTPS connections are often used for transaction payments on the World Wide Web and for the transmissi

In the previous blog, the first step in speaking of SSL was to create a certificate. (or buy from a third party) PS: The final on-line product, the certificate will be to the Third-party certification body to buy, but in the development process, is created by themselves. The common tool for creating certificates is Keytool, a JDK-only tool that can be used if the computer is installed with JDK (and the environment variables are configured). Linux syst

SSL: (SecureSocketLayer, Secure Socket Layer) is a protocol layer between reliable connection-oriented network layer protocol and application layer protocol. SSL authenticates each other, uses digital signatures to ensure integrity, and uses encryption to ensure privacy, so as to achieve secure communication between the client and the server. The protocol consists of two layers:
